Clinical trials-related knowledge, attitudes, and behaviors among Black and Latina women: A randomized controlled trial of the Women United: Clinical Trials and the Fight Against Breast Cancer Program.

Black and Latino adult cancer patients are underrepresented in cancer clinical trials, which limits generalizability of findings and amplifies disparities in healthcare access and outcomes. Community-level education programs designed to address barriers to participation could improve representation in cancer clinical trials. Through a community-campus partner framework, this study evaluated the Women United: Clinical Trials and the Fight Against Breast Cancer Program in Spanish and English. Participants were 422 women (141 Black, 140 Latina Spanish preference, 141 Latina English preference) who were randomized to view either the intervention (n = 215) or a control (n = 207) program. Assessments of clinical trials knowledge and barriers to clinical trials participation were taken before and after viewing. Results suggested that clinical trials knowledge increased and perceived barriers to participation decreased for those who viewed the educational program. More specifically, those in the intervention condition perceived fewer barriers related to personal benefits, mistrust, and familiarity of clinical trials. As expected, there were no differences in perceived barriers related to community support for either condition. Participants in both conditions were equally likely to join a subsequent study or a clinical trials community ambassador program. There were no differences in any of the outcomes across ethnicity or language, suggesting the program works equivalently across groups. This program is easy to administer and can be recommended for use among Black and Latina women to address factors related to clinical trials participation.
